Martindale Abrasion & Pilling Resistance Test Method

Author: Released in:2018-05-22 Click:310

Martindale abrasion tester working principle:
Test piece of fabric is placed in the specimen clamp, and it will be rubbed against with abradant in a Lissajous figure. According to the requirement, once the test piece is broken, test piece should be taken down to calculate its abrasion resistance index, or evaluate its rating of pilling through the visual description.

Test procedure:
1、Test piece preparation
In the standard environment, we put the test piece in the tiled state for a period of time according to different standard. For example, 24h (GB/T 4802.2), 16h(EN ISO 12947-4).

2、Test piece selection
The representative test piece is cut from different positions of width. But we need to cut the sample with different fabric and color if fancies is as material.

3、Taking down the additional loading weight and bearing axle.

4、Taking down the top and clamp holder.

5、Test placement
Loosening the retaining ring of test clamp, we should put the test piece into the test clamp base. If the test piece is smaller than 500g/m2, we need to put a foam between the test piece and the metal clamp. Oppositely, it is big enough, or it is compound fabric, we don’t need the foam. Each piece held in test clamp should get the same tension.

6、Placement of wool felt and abradant
Putting the wool felt and abradant on the holder, and the additional loading weight on the abradant, and then tighten the nut in order to fasten the abradant on the holder by retaining rings.

7、Pressing the abradant on the pressure head.

8、Let the side of test clamp with test piece face down, and put it on the test clamp base. After that, the bearing axle should be adjusted until it aligns and inserts the circular groove of clamp.

9、According to standard, we settle the number of times on the tester and turn on it. Won’t be stop itself until it achieves enough times in the measurement.

10、Taking down the test piece and compare it with photographic standard.
